Frequently asked questions
What is the classic sepia color transformation formula?
The filter computes output channels using weighted matrix formulas: R = 0.393R + 0.769G + 0.189B; G = 0.349R + 0.686G + 0.168B; B = 0.272R + 0.534G + 0.131B, clamped at 255.
Can I adjust the intensity of the sepia warmth?
Yes. You can blend the sepia matrix against the original colors to achieve anything from a subtle warm glow to full antique toning.
Are sepia photos saved as color or monochrome files?
Sepia tones contain warm reddish-brown chromatic hues, so the output file is saved as standard RGB color rather than single-channel grayscale.
